You could certainly leave it be the way it is, but if it irks you, the top can be hacked off. It needs to be done a specific way, to ensure the best odds, that your aloe will survive though. I have been know in the past to cut the tops off aloes, and re-root them with great success. This is how I do it:
1. Cut the top off the aloe to desired length (preferably with something sterile)
2. Remove some bottom leaves, so a stem like part can be created to hold the aloe up in the soil.
3. (This is the most important step) Set the cutting somewhere cool, and without direct sunlight for a minimum of one week. This will allow the cut part to dry and callus properly. If not dried enough, the chances of it rotting when planted skyrocket.
4. Then just plant it in some well draining substrate, and keep it out of direct sunlight. Do NOT water yet.
5. After a minimum of one week being planted, you can give some water to settle everything.
6. After this, you can pretty much treat it like a normal plant, letting it dry out before watering. Just remember that dry soil encourages root growth, so you may want to water sparingly at first. That's what you need. Root growth.
I typically don't hack my aloes anymore, and just let them grow into little aloe trees, but sometimes it is called for. In your case, I would probably hack it, but your choice. Best of luck to you, and please keep us updated
